“College rock” as a category of alternative music might seem like a misnomer in 2016—campus stations these days are mainly shriveled appendages of the grandstanding blogosphere, more than happy to peddle acts who are already thoroughly established—but in its ’80s pre-internet heyday, college radio provided a real alternative to the barren mainstream airwaves (which is perhaps proof that an artistic countermovement can only be meaningful when the prevailing artistic culture is totally fucking vapid). Tonight’s two shows feature a handful of great and diverse Portland acts paying tribute to alternative rock’s forebears: heavyweights like the Smiths and the Smithereens (obviously), but hopefully also underrated icons of the era like the dBs, Let’s Active, and XTC. Tonight’s two shows are also benefits for p:ear, an organization that pledges to form relationships with homeless and transitional youth through art and education. MORGAN TROPER
